owest.

To all whom it may concern .Be it known that I, Jenn FRANKLIN KIL- ernur, a citizen of the United States, and a resident of El Paso, in the county of El Pass and State of Texas, have invented a new and Improved ell-Cleaning Device, of which the following is a full, clear, and exact description.

This invention-relates to pumping apparatus for wells and has particular reference to means or appliances for such wells which are adapted to insure perfect and constantly satisfactory operation of wells of any depth which may be dug or drilled in the .vicinitj of quicksand or other sedimentary matter which so frequently clogs up the working barrel and causes the stoppage of the pump.

Among the objects of this invention, therefore, is to provide a pump or an attachment for a pump having provision for conveying to theworking barrel a fluid under pressure which will serve to break up the accumulation or deposit of sand or the like at the bottom of the pump and cause such sand to be delivered upward through the well casing and hence out of osition to cause retardation or stoppage o-' the apparatus.

The invention furthermore comprises certain details of construction whereby the foregoing object is carried out in a practical and commercial manner.

The foregoing and other objects ot the invention will hereinafter be more fully de scribed and claimed and illustrated in the drawings forming a part of this specifics tion in which like characters of reference in dicate corresponding parts in all the views, and in which Figure 1 is a side elevation of sufficient of my pump apparatus to illustrate its principle of o oration, certain parts being in section an others being broken away; Fig. 2 is a vertical section of one form of Working barrel and indicating the valve mechanism in side elevation; Fig. 3 is a transverse section on the line 33 of Fig. 2; and Fig.

4 is a vertical section of amodified'form of I working barrel.

The several parts of the apparatus may he made of any suitable materials and the relative sizes and proportions of the same may be varied to a considerable extent without departing" from the spirit of the invention hereinafter claimed. f

Referring more particularly to Fig. 1, I

Specification of Letters Patent.

Application filed February 27, 1913. Serial No. 756,986.

Show at 10 a well casing extending to any suitable depth into the earth and inclosing a pump casing 11 of any well known or approved construction. The pump casing is provided at its lower end with a working barrel 12 having a foot or check valve 13 and a plunger 14. Any well known or ap proved form of pump rod 15 extends downwardlv through the pump casing and is connected to the plunger 14. The parts so far described are or may be of any ordinary or conventional form.

Inthose localities in whit h there. is a troublesome amount of quicksand which finds its Way along with the water or other fluid being pumped into and through the working barrel and pump casing, there is a common source of annoyance due to the fact that the sand or other heavier particles, when the pum is standing idle for a short time, will sett e at the bottom of the pump casing and so clog or obstruct the operation of the plunger and particularly the sucker valve 16 to render the pump useless. This necessitates the removal of the pump rod and plunger, if it is possible to so remove them from the casing, or more frequently it is re uired that the entire pump casing must e removed in order to dislodge the sand. This entails enormous expense to say n'ot-hingof the loss of time and trouble incident to the fact that the well is disabled for a number of days while the pump is beingreiioved of the con estion. In order to overcome the difficulty herein recited, there fore, I provide a means for introducing water, oil, steam or air into the Working bar.- rel under high ressure. For convenience of description, will hereinafter employ the expression fluid under high pressure as covering generically any of the species of fluids which may be employed under various circumstances for the purpose set fouth. I desire to state, however, at this point that ordinarily for the purposes of convenience and economy, such fluid will be water to which pressure or head may be givep because of anelevated tank.

I show at 17 a pipe connected through an elbow 18 and nipple 19 to the working harrel adjacent the check valve 13, said nipple being adapted to deliver the high' pressure fluid into and through the cage of the foot .valve and above the ball 21. The ball, however, will not be unseated by such fluid,

so I

but the accumulation of sand above the ball will be agitated, loosened and conveyed up- Wardly through the pump casin and thence 'out through the discharge pipe 22 along with the water which may be con-' tained in the casing together with theactuating tluid.- Said pipe 17 leads downwardly from an elevated tank 23, according to the present illustration, which may be kept supplied with water by any suitable means asv slight flow of the high pressure fluid is re quired or is su'llicient, the valve 26 is opened, but when the maximum flow of the same is demanded, the other valve 2-1 is opened. When the accumulation of sand or the like has become excessive as, for instance, when the apparatus has been standing idle overnight, it is necessary to introduce high pressure fluid into the Working barrel in the region of the sucker valve 16 or above the plunge-1'. F or this purpose I provide an.

auxiliary emergency pipe 27 leading from the tank 23 down within the well casing and delivering into the working barrel through a nipple 28, as indicated in Fig. 2. This pipe 27, like the pipe 17, is of relatively small diameter, and connected as shown, will relieve any case of congestion due to the causes above enumerated. Said pipe 27 also is provided with a main valve 24, a by-pass 25 and an auxiliary valve 26 having functions similar to those already described.

I provide as a' preferred construction in connection with the nipples l9 and 28, a

pair of reinforcing bands or rings B. Each of said rings surrounds the working barrel and is tapped so that'the nipple passes through it as well as the wall of the barrel.

In Fig. {I I show a working barrel 12 which may be regarded as an appliance ters Patent :79

1. In a device of the class set forth, the

combination with pump mechanism'includtion. The working barrel 12' may. be made of any suitable material and is preferably bored 'or cored at 29 and 30 to provide passageways to which the pipes 17 and 27 respectively are connected and through which said pipes deliver high pressure fluid into the working barrel Til the region of the cages of the foot valves and sucker valves 13 and 16 respectively. The operation in this form of the invention is substantially the same as that already described.

Having thus described my invention, I claim as new and desire to secure by Let combination of a working barrel, a foot valve therein, a plunger and sucker valve above the foot valve, and means tode'liver fluid under lpgh pressure intoand through 7 different parts of theworking barrel and into the region, of the respective valves,

said fluid delivering means including longitudinal passageways formed 1n and through the wall'of the working barrel and 30 communicating with the interior thereof just above said valves and tubes tapped into the ends of said passageways.

2. In a device for cleaning wells, the

(mg a p'ump casing and a. working barrel connected thereto, ,of means for delivering fluid under-high pressure to and. through the wall of the working barrel, said fluid delivering means including a pipe leading down into the well on the outside of the pump casing, and a plurality of valves to control the passage of high pressure fluid therethrough, substantially as set forth.

In testimony whereof I have signed my 95 name to this specification in the presence of ,two subscribing Witnesses.
